GEORGE W. GWINN, OF BROOKLYN, NEXV YOBK, ASSIGNOR- TO AUTOMATIC PACKING & LABELING COMPANY, OF DURHAM, NORTH CAROLINA, A CORPORATION OF NORTH CAROLINA.

To all whom it may concern:

Be it known that I, GEORGE IV. GWINN, a citizen I of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Measuring-Pans, of which the following is a specification.

This invention relates to an improvement in measuring pans, particularly of the type used in. automatic machines for weighing and packaging tobacco and other substances having similar characteristics.

Certain tobacco weighing machines known in. the art are provided with a measuring pan which forms a part of a scale, the tobacco beingdeposited in the pan of the scale and then dumped thereby into suitable mechanism forinclosing the weighed tobacco in a suitable package. In weighing certain kinds of tobacco with scale pans heretofore used. considerable difiicu'lty has been experienced in keeping the scales accurate because the sticky juices of'the tobacco cause fibers or pieces thereof to stick to the pan or to other pieces already stuck to the pan when a measured quantity is dumped into the mechanism for packaging the same. As the operation of such machine continues, tobacco thus accumulates in the pan; This'a'ccumulation of tobacco must be frequently removed to prevent inaccurate weighing, and such removal involves loss of time and r,e duced efficiency. The main object of the in vention is the production of a measuring pan provided with a simple device for automatically preventing by a wiping action the accumulation of tobacco in the pan. With this and other objects not specifically mentioned in view, the invention consists in certain constructions which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a central sectional View of a device constructed in accordance with the invention; Fig. 2 is a similar view but turned to dumping position; Fig. 3 is a front view of the device shown in Fig. 2; and Fig. 4. is a side elevation of a device similar to that illustrated in Figs. 1, 2, and 3, but provided with a handle whereby it may be used as a scoop in handling sugar or other more or less sticky substances.

MEASURING-PAN.;

Specification of Letters Patent. Patented 1y 272, 1919 Application filed April 4, 1918. Serial No. 226,581.

In carrying the invention into effect, there 18 provided a measuring pan provided with a flexible wiper normally overlying or resting upon the bottom of the pan, one end of said wiper being fastened to the pan in positlon to cause a relative wiping action of the wiper and pan when the latter is tilted to empty the same. In the best constructions, a wiper is fastened to the rear end and above the bottom of the pan and consists of a series of leather thongsv which may be treated with oil to render them permanently soft and pliable, if desired.

Referring to the drawings, 5 indicates a shaft which is a part of the scale mechanism of a weighing machine provided with suitable mechanism for rocking said shaft. This weighing machine and mechanism lies wholly outside of the present invention; and since a description of its particular mechanism is not necessary to a'full understanding of the present invention, such description is omitted in the interest of brevity and clearness. Fast upon the shaft 5 are a pair of lugs 6 riveted or otherwise secured to the lower part of the side walls 7 of a measuring pan supported by and forming a part of the scale mechanism above referred to. The upper part ofthe walls 7 are or may be flared outwardly at 8. The pan is in the form of a scoop and has a concave bottom 9 and a wall 10 at its rear end. The'pan is constructed of metal and has a smooth interior surface. Normally overlying the bottom of the pan is a series of leather thongs 11 which, as shown, are formed by slitting a strip of leather throughout the greater part of its length. The unslitted end of the leather strip is clamped to the wall 10 by means of a clamping plate 12 and screws 13. For the purpose of makingthe thongs permanently soft and flexible, they may be oil treated.

In Fig. 1, the device is shown in tobacco receiving position, the tobacco overlying the leather thongs resting upon the pan bottom. When the shaft 5 is rocked to turn the pan to the position shown in Fig. 2, the leather thongs slide along the bottom of the pan carrying the tobacco'with them and eventually leave the bottom and hang clear therefrom, as shown in Fig. 2. The pan is returned to tobacco receiving position by a quick rocking movement of the shaft 5 in the opposite direction. The thongs swing about thus produced keeps the interior surface of the pan smooth and highly polished, and prevents the tobacco from sticking thereto, so that in the use of the device there is no loss of time and no resultant production loss due to tobacco accummulation.

The device illustrated in Fig. 4 is similar 'tothat shown in Figs. 1, 2 and 3, but is intended for hand use and the pan marked 14 is therefore provided with a suitable handle 15 extended from the rear Wall of the pan and by means of which it may be operated.

Changes and variations may be madein the device by means of which the invention is carried into effect. The invention therefore is not to be restricted to the precise details of the structure shownand described.

What is claimed is: p

'1. A measuring pan provided with a flexible wiper normally resting upon the bottom of the pan, one end of said wiper being fastened to the pan in position to cause a relative wiping action of. the wiper and pan when the latter is tilted to empty the same. I i

2. A measuring pan provided with a flexible wiper normally resting upon the bottom of the pan, one end of said wiper being fastened to the rear end of the pan and in position to cause a relative wiping action of the wiper. and pan when the latter is tilted to emptythe same.

Gopieso! this patent may he obtained for five cents each, addressing the 3. A measuring pan provided with a flexible wiper normally resting upon the bottom of the pan, one-end of said wiper being fastened to the rearend and above-theboe Y tom of the pan to cause a relative wiping action of the wiper and pan when the latter is tilted to empty the same.

' A measuring pan having a rear end wall and provided with a fiexible wiper normally resting upon the bottom of the pan, one end of said wiper being fastened to the top of said rear end wall.

5. A measuring pan having a rear end wall and provided with a series of flexible wipers normally resting upon the bottom of the pan, one end. ofeach wiper being fastened to the topof said rear end wall.

6. A measuring pan having a rear end wall and providedlwith a series of leather thongs normally resting upon the bottom of the pan, one end of each thong being fastened to the top of said rear end wall;

7. A measuring pan provided with a wiper treated with oil to render it permanently soft and flexible, said wiper normally resting upon the bottom of the pan with one of its ends fastened to said pan in position to cause a relative wiping action of the wiper and .pan when the latter is tilted to empty the'same. V 8. A measuring pan having a rear end wall and provided with a series of leather thongs treated with oil to render them permanently soft and flexible, said thongs normally resting upon the bottom of the pan with one end of each fastened to the top of said rear end wall. v

In testimony whereof, I have signed my name to this specification.
